Supersymmetry, Supergravity and Superstrings (Physics)

提出研究相对论弦理论的各个方面，其最终目标是统一量子引力理论和其他基本相互作用。(1)经典和量子二维世界片超对称非线性σ模型将用于弦理论中玻色子场的低能行为研究。(2)时空超对称的超空间公式将用于构造明显超对称的有效作用，使sigma模型的计算结果扩展到包括费米子。(3)将进一步研究相对论量子场论协变描述的BRST形式。

It is proposed to study various aspects of the theory of relativistic strings, which have the ultimate objective of a unified quantum theory of gravity and the other fundamental interactions. (1) Classical and quantum two dimensional world- sheet supersymmetric nonlinear sigma models will be used to study the low energy behavior of bosonic fields in string theories. (2) The superspace formulation of spacetime supersymmetry will be used to construct manifestly supersymmetric effective actions, allowing results of sigma model calculations to be extended to include fermions. (3) The BRST formalism for the covariant description of relativistic quantum field theories will be studied further.
